Hey man! I have a Pair of Abstract Acoustic Speakers> And i have had them for about 6 years. And i seem to know more than Everyone i have ever talked to. LOL So yeah.. IF you got a question Ask me.> As for Quality. They are Fantastic. Like i would buy Any of them on the spot if i saw them.

I have an old Abstract Acoustics subwoofer. Abstract Acoustics was made by a Toronto company called Audiosphere in the 1980s and is now out of business. They were generally lousy speakers (sorry to say).

I just picked up a pair of Abstract Acoustics speakers, the ASX-PRO.800 model. I grabbed them for next to nothing, the previous owner kept them in impeccable shape for such old speakers - nary a scratch on them. The drivers are all fresh and compliant, I would have thought at this point I'd need to re-foam them - but they are good as new. This set has Japanese drivers in them, thought it would be Chinese for sure. Nothing like dual 12" woofers to rumble the place. I love how gems like these are overlooked by the audio snobs,

Their audio tone is a bit bass heavy but not boomy - that's why I bought them though. I'm sort of tired of the neutral KEFs, Focals and Fluance speakers I've owned in the past. Reference speakers have a way of being a bit too vanilla for me. I want more of a colored bass tone that's warm, smooth and rolls off well but still captures those low lows - like the AR9s in my den. I'm a big fan of acoustic suspension design, but these bass reflex do a decent job regardless. Most of the higher end speakers have dual tiny 6" bass drivers and are essentially tinny sounding without their matching sub-woofers. You don't need subs with the dual 12" woofers in these ASX speakers. But they have two ports instead of the usual 1 that usually accompanies dual 12" woofer designs of this era. I may experiment and block off the second port to see if the bass can be reduced just a little.

The mids aren't muddy or muffled as I expected them to be, they are open and clean and have as much definition as my KEFs ever did. Highs are crisp and smooth - another surprise as I was expecting harsh and peaky and was all set to replace the tweeters. I was looking for resonant bass and this is where it's at. So nice not to have to use a sub as a crutch. Over the years, I've noticed that the most resonant cabinets for the average 16'x20' room needs to be about 14" in depth - these enclosures qualify and it's evident in their tone.

It took some time to find their room placement in order to have them project evenly. Once I found it, they became much more neutral but still with that bottom end that smaller drivers just don't have.

They have 2 issues: the bass is a little too directional, it changes quite a bit as one walks around the room, but that could be because I'm used to my AR9s which have dual 12" side-firing woofers. The second is they need more insulation which I plan to address soon. Overall, an excellent buy for the lunch money I spent on them.

Goes to show you the longevity & durability of some decent brands that many audio snobs just sniff at. Someone else will probably buy a set in the future and this thread will be revived 5 years from now.

I have a set of the asx-pro 400 that I bought new about 18 years ago and still work very well. only issue I ever had was the tweeters. they blew about a week after I got them. the retailer was nice enough to pull the pair out of another set they had in stock, but they blew again shortly after. I currently have replaced them with some focal car audio tweets I had and sound even better.
same story, bass is big. the 12's pound. I disabled my sub and it's better than with.. currently powered by 2 year old onkyo receiver.

Funny you should post now. I just finished swapping out the stock 12s with these Faital Pro 12s. I was looking to reduce the boominess and it worked. At first I thought it was the way the bass ports were tuned, but it's just the drivers.

When I first put them in, they sounded much flatter but there was something missing - and it's because I had turned down the bass on my amplifier in an effort to reduce the boominess of the old drivers. Once I leveled the bass back to neutral, they now sound exactly like I want them to sound.

As for your comment on dual 12s, I agree. I used to drag full Marshall stacks to the studio (8x12") and my bassist used a 4x15" cabinet. How today's speakers with their puny 6" and 8" drivers plus a single 10" or 12" sub hope to duplicate that big studio sound is beyond me - it just won't. One needs at least dual 12s per speaker to make it sound like it should. And having no sub keeps the sound more cohesive. I have a 15" AR sub I occasionally use but it's really not needed when you've got four 12" woofers. I have a similar setup in my car.
